Question

Can the number reduce to 0 ?How many times can u repeat the operation?Is the number reduced permanently?What are the ill effects after certain no. of yrs.?

Answer 1

laser operation is based on the principle that laser has the ability to burn living cells..and hence used to burn the bulged portion of the retina which results in corrected vision.....there are no side effects as long as the person handlin the laser gun is experienced enough not to miscalculate the dosage and direct it well

Answer 2

Laser vision correction is surgery - please understand that. Companies that don't include the word "surgery" in their advertisements should be avoided; they want you to think it's something simple without many risks.

There are lots of risks.

The biggest risk, of course, is complete blindness. They actually use a laser to cut into the layers of tissue over your eyeball. This means there's a risk of infection and a risk that your vision will be even worse than it started out. Sometimes people scar badly when healing, and this can create blindspots and blurry vision that is not correctable.

Side effects can include dry eyes, usually temporarily but for some people it can be permanent. Others include eye pain and headache. Vision will be blurry for most people for a day or two. Some people will experience poor depth perception.

For some people, laser correction can make their vision better than 20/20 (considered "perfect"). Our eyes, like the rest of our bodies, continue to change as we age. Therefore, our prescriptions may get worse again as time goes by. This is not because the procedure failed, but because nothing can stop us from aging. Most people still have better vision than they originally did, which can mean that they can use a much lighter lens prescription and/or have a wider variety of frame options. Some companies offer free "touch ups" for various lengths of time. Good companies won't perform the procedure unless your prescription has been stable for a few years.

Beyond the immediate risks and side effects, there are no long-term consequences of laser correction, as far as we know.

People who smoke or who have uncontrolled diabetes, for example, have a higher chance of experiences complications.

All that said, most people have no problems when they go through laser correction. Just make sure you know the risks - they DO happen, and COULD happen to you.
